Fashions or ways of doing things (6)
![Ross](/clue/static/ross-mug.min.png)
I believe the answer is:
styles
I believe this is a double definition.
'fashions' is the first definition.
(I know this)
'ways of doing things' is the second definition.
(I've seen this before)
(Other definitions for styles that I've seen before include "Fashions and manners" , "where there was a mysterious affair involving Poirot" , "Fashions or ways of doing things" , "Distinctive manners" , "'Fashions, modes (6)'" .)
